STRAINER FOR DlSCHARGE-SPOUTS FOR WASHBASINS.

SPECIFICATION forming part of Letters Patent No. 572,788, dated December8, 1896. Application filed anuary 28, 1896. Serial No. 577,193. (Nomodel.)

To all whom it may concern.-

Be it known that I, ALEXANDER DUKE, a citizen of the United States, anda resident of Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Strainers forDischarge-Spouts for Washbasins or the Like,

ward direction and so as to rest on a cross.

, bar thereof and which is formed integral with offsets adapted toimpinge against the inner surface of the mouth of the spout for thepurpose of retaining the strainer therein, thereby dispensing withextraneous fasteners and at the same time preventing its accidentaldisplacement, as hereinafter more fully set forth, and illustrated inthe accompanying drawings, in which-- Figure 1 represents a plan view ofthe strainer detached. Fig. 2 represents a like view thereof as itappears when applied to a spout. Fig. 3 represents a vertical section ofthe spout with the strainer therein. Fig. 4 represents a plan view ofthe strainer de- 'tached and provided with a finger-button.

Fig. 5 represents a side view of the strainer shown in Fig. 4. Fig. 6represents a top view of the disk, omitting the ofisets.

Similar letters of reference indicate corresponding parts.

The letterAindicates the body of the spout, which is of substantiallythe usual form,with an external screw-thread and a circumferentialflange at its upper edge. Within this body A are two cross-bars B 0,extending at right angles to each other, and on the upper one of thesebars, B, rests the sieve or strainer D. This strainer D is a piece ofperforated sheet metal or other suitable material in form of a disk andis fitted loosely into the spout from an upward direction, so as topermit of its ready introduction into and removal from the spout, and itis held in place within the spout by means of lugs or ofisets e, whichare formed integral therewith and in such a manner as to impinge againstthe inner surface of the spout, thereby engaging therewith by frictionalcontact. The sieve thus arranged obviously prevents the entrance ofsolid matter into the spout, with the effect of obviating the chokingthereof, while it may be readily renewed when deemed necessary Withoutaffectin g the remainder of the spout, inasmuch as it is free from anypermanent connections. With a view to facilitate the introduction orremoval of the strainer from the spout it may be provided withthumb-piece or handle f, as shown in Figs. 4 and 5.

In carrying out my invention I form the strainer with its lugs oroffsets e in one and the same piece, and then by forcing the strainerinto the spout cause its lugs to bend upward and thus impinge againstthe surface of the spout in the desired manner.

Referring to Fig. 6, the strainer or sieve is a piece of perforatedsheet metal in the form of a disk, omitting the lugs e, and which isheld inplace under normal conditions by its inherent gravity and also bythe tendency of the water flowing through the spout to force it onto itsseat.

That I claim as new, and desire to secure by Letters Patent, is-

A spout for a washbasin having in combination with a cross-bar therein asieve D of perforated material of disk form with lugs e in one and thesame plane and made integral therewith in such a manner as to impingeagainst the inner surface of the spout by frictional contact of theoffsets e and so as to rest on the cross-bar when introduced from anupward direction leaving a space between the periphery of the disk andthe inner surface of the spout, and provided with a handle f tofacilitate the introduction and removal of the strainer from the spout,substantially as shown and described.
